The structure of analcite and ion-exchanged forms of analcite

From a consideration of the accepted structulre of analcite it is shown that this mineral need not necessarily be considered as having an averaged lattice.The structure of leucite, and other ionexchanged forms of analeite, is discussed in relation to the known data on pollucite, leucite and analeite.The importance of the degree of hydration of the various ion-exchanged analcites is mentioned.
